Symantec Response
Symantec engineers have verified and fixed this vulnerability. The following steps are required for remediation of this security issue:

Run under the principle of least privilege where possible to limit the impact of exploit by threats.

Keep all operating systems and applications updated with the latest vendor patches.

Follow a multi-layered approach to security. Run both firewall and anti-malware applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats.

Deploy network and host-based intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in detection of attacks or malicious activity related to exploitation of latent vulnerabilities
